The laryngopharynx extends from the superior border of the epiglottis to the inferior border of the cricoid cartilage, where it becomes continuous with the esophagus.
The pharyngeal ridge is an elevation or bar on the posterior wall of the pharynx inferior to the level of the soft palate; it is produced during swallowing by transverse muscle fibers.
The epiglottis is attached by ligaments to the hyoid bone, to the posterior aspect of the tongue, to the sides of the pharynx, and to the thyroid cartilage.
This means that our practice encompasses microsurgery on the vocal folds as a large part on one end of the spectrum, up to and including the big operations of larynx cancer and larynx and tracheal reconstruction, on the other end of the spectrum.
Laryngopharynx: Refers to the anatomical region that begins roughly at the base (back) of the tongue and goes down to the level of the upper part of the trachea/esophagus low in the neck.
Laryngopharynx reflux disease: A constellation of symptoms and findings caused by reflux (backwards flow) of stomach acid into the throat or larynx, typically during sleep.

The laryngopharynx lies posterior to the larynx, and is continuous with the esophagus.
For instance, fibers donated by X are the motor component, whereas IX generally provides the sensory component in the oropharynx and laryngopharynx, but X is sensory to the lowermost portion of the pharynx.
Lastly, the laryngopharynx is supplied by branches from the ascending pharyngeal artery.
Because the paranasal sinus area lies in an anatomically complex region, tumors in the paranasal sinuses can invade a variety of structures- such as the orbit (the bony cavity protecting the eyeball), the brain, the optic nerves, and the carotid arteries- even before symptoms appear.
The pharynx (throat) is divided into three sections: the nasopharynx, oropharynx, and laryngopharynx.
The oropharynx is the area posterior to the mouth.
Advanced Cancer Laryngopharynx in patients with anaesthetic problems and those unwilling to have a permanent tracheostomy are offered this mode of treatment.
As the airway is surgically cleared this does not cause stridor and permanent tracheostomy is avoided.
A) Pre operative Laryngopharynx with malignant growth – T3 No Mo and stridor.
While typically there is an associated odynophagia, physical examination of the oral cavity and laryngopharynx will reveal erythema, edema and sometimes an exudate.
Physical exam is remarkable for effacement of the angle of the mandible on physical examination of the neck, as well as medial displacement of the lateral pharyngeal wall on endoscopic examination of the laryngopharynx.
Viral infections of the oral cavity and laryngopharynx can cause dysphagia directly from lesions along the mucosal lining of the upper aerodigestive tract, or indirectly secondary to cranial nerve damage as a consequence of viral infiltration of upper cranial nerve ganglia.
MICHAEL E. Anesthesia or hypesthesia in the laryngopharynx following stroke or injury to the internal superior laryngeal nerve (ISLN) can result in dysphagia, aspiration, pneumonia, and/or death.
Attempts to reinnervate an anesthetic laryngopharynx have not established accurate cortical representation of sensation or reconstituted the laryngeal reflexes.
The purpose of our study was to 1) determine if there is a consistent branching pattern of the ISLN; 2) map, with the use of electrophysiological testing, the mucosal receptive fields of such conserved branches; and 3) identify branches that might serve as both donor and recipient nerves of a restorative nerve graft.

No dyspnea caused by the air passage defect even on activity requiring prolonged exertion or intensive effort.
(3) Objective findings of one or more of the following air passage defects: Partial obstruction of oropharynx, laryngopharynx, larynx, trachea, bronchi, complete obstruction of nasopharynx or of nasal passages bilaterally, dyspnea caused by the air passage defect produced only by prolonged exertion or intensive effort.
(4) Objective findings of one or more of the following air passage defects: Partial obstruction of oropharynx, laryngopharynx, larynx, trachea, bronchi, complete obstruction of nasopharynx or of nasal passages bilaterally, with permanent tracheostomy or stoma, dyspnea caused by the air passage defect produced only by prolonged exertion or intensive effort.
(3) Objective findings of one or more of the following air passage defects: Partial obstruction of oropharynx, laryngopharynx, larynx, trachea, bronchi, complete obstruction of nasopharynx or of nasal passages bilaterally, dyspnea caused by the air passage defect produced only by prolonged exertion or intensive effort.
(4) Objective findings of one or more of the following air passage defects: Partial obstruction of oropharynx, laryngopharynx, larynx, trachea, bronchi, complete obstruction of nasopharynx or of nasal passages bilaterally, with permanent tracheostomy or stoma, dyspnea caused by the air passage defect produced only by prolonged exertion or intensive effort.
(6) Objective findings of one or more of the following air passage defects: Partial obstruction of oropharynx, laryngopharynx, larynx, trachea, bronchi, with or without permanent tracheostomy or stoma if dyspnea is produced by mild exertion.
examination reveals partial obstruction of the oropharynx, laryngopharynx, larynx, upper trachea (to the fourth cartilaginous ring), lower trachea, bronchi, or complete (bilateral) obstruction of the nose or nasopharynx
examination reveals partial obstruction of the oropharynx, laryngopharynx, larynx, upper trachea (to the fourth cartilaginous ring), lower trachea, or bronchi
examination reveals partial obstruction of the oropharynx, laryngopharynx, larynx, upper trachea (to the fourth cartilaginous ring), lower trachea, and/or bronchi
Before you can alleviate symptoms in patients with LPR and ensure healing of the laryngopharynx, you must understand the differences between LPR and GERD.
The author works in the otolaryngology-head and neck surgery division of Allegheny General Hospital, Pittsburgh, Pa. She has indicated no relationships to disclose relating to the content of this article.
The term LPR is used to describe the acid in the stomach that comes up into the throat at the level of the laryngopharynx.
